The YASKAWA SERVO MOTORS 400W BREAK SGM7J-04AFC6E is a state-of-the-art servo motor engineered for precise torque and speed control in modern industrial automation systems. Part of the renowned Sigma-7 family, this 400-watt model integrates a high-resolution 20-bit absolute encoder for exceptional positioning accuracy, while the built-in electromagnetic brake provides secure holding in vertical or high-inertia loads. Ideal for applications requiring compact dimensions and rapid acceleration, the SGM7J-04AFC6E delivers consistent performance across a wide speed range, from low-speed creep to high-speed operation. Its advanced magnetic circuit design minimizes cogging torque, ensuring smooth motion even at low RPMs. With a rated torque of 1.27 N·m and a maximum torque of 4.46 N·m, this motor is well-suited for machining centers, robotics, and printing machinery. The unit features a standard flange size (80 mm square) and a shaft diameter of 14 mm with keyway, facilitating easy integration into existing mechanical systems.
